ASTM B75 C12200 copper alloy tube is a seamless, cold-drawn phosphorus-deoxidized copper (Cu-DHP) tube designed for general engineering service and particularly well suited for steam tracing and low- to medium-temperature steam lines.
The alloy (UNS C12200 / Cu-DHP) combines:
Very high copper purity (≥99.9% Cu including Ag) with 0.015–0.040% phosphorus as a deoxidizer, ensuring resistance to hydrogen embrittlement and good weldability.
Excellent thermal conductivity and good corrosion resistance in typical steam and condensate environments.
This makes it a robust and economical choice for steam tracing of process pipelines, valves, instruments and ancillary equipment.
Grade & Standard

Manufacturing Process
Seamless, hot-worked and cold-drawn tube
Supplied either:
Fully annealed (soft coils / straight lengths)
Light-drawn or hard-drawn on request
Typical Dimensions for Steam Tracing
(Design-dependent; below are common tracer sizes)
Outside diameter (OD): 3/8" (9.52 mm), 1/2" (12.7 mm) commonly used; 1/4"–7/8" OD available

Length:
Level-wound coils: up to 50–150 m per coil (typical)
Straight lengths: 3–6 m standard; custom on request
Delivery Condition & Finish
Temper: O60 (soft annealed) is preferred for steam tracing due to easy bending; hard tempers (H55/H80 etc.) available where higher strength is required
Ends: Plain ends, deburred; other end preparation upon request
Surface: Clean, bright or light oxide, internal cleanliness controlled for steam and condensate service
Optimized for Steam Tracing Temperatures
C12200 copper tube under ASTM B75 is widely used in fluid and steam lines and retains strength at elevated temperatures typical of low- and medium-pressure steam service.
Excellent Thermal Conductivity
High thermal conductivity (around 196 W/m·K) enables efficient heat transfer from steam to the traced line, reducing the number of tracers and steam consumption.
Resistance to Hydrogen Embrittlement
Phosphorus deoxidation minimizes dissolved oxygen and prevents “steam embrittlement” (hydrogen disease), a key requirement for copper in hot, moist service.
Strong Corrosion Resistance in Steam/Condensate
C12200 and related Cu-DHP alloys exhibit very good resistance to general corrosion and pitting in water, steam and many industrial atmospheres, supporting long service life in steam lines and tracers.
Easy Bending, Forming and Joining
Excellent cold-workability and brazing/soldering characteristics allow tight-radius bends, coiling around process pipe, and reliable joints (brazed, soldered, compression fittings).
Proven Standardized Quality
ASTM B75 specifies mechanical tests, hydrogen embrittlement testing, expansion tests and non-destructive (eddy-current / pressure) tests for copper tubes, ensuring consistent, traceable quality.
Cost-Effective vs Stainless for Moderate Conditions
For many designs, copper tracer tube is recommended for steam service up to about 400°F (204°C) where compatible with the medium, offering lower material and installation cost than stainless steel.
Based on common questions from engineers and buyers of steam tracing tubing, here is how this product and our supply approach address key concerns:
Engineering guidelines indicate copper tubing is suitable when saturated steam temperature does not exceed about 400°F (204°C) and when the process or environment is not aggressively corrosive.
Our C12200 tubes are supplied in wall thicknesses selected according to your design pressure and applicable piping codes; heavier walls can be provided for more severe thermal cycling as recommended by steam tracing best-practice documents.
What we offer
Application review (steam pressure, temperature, medium, environment) and guidance on when C12200 copper is ideal and when 316L stainless tracer tube is a better choice.
Wall-thickness selection and documentation to align with your internal standards and project specifications.
Design guides point out that copper is economical but corrosion products can contaminate traps and instruments if water chemistry is poor.
Our approach
We supply C12200 from controlled-chemistry Cu-DHP melts with very low impurity levels and proven service in steam, water, and heat-exchange systems.
On request, we can provide:
Pre-cleaned / internally cleaned tubes for critical steam/condensate systems
Guidance on compatibility with your condensate treatment program
Alternative 316L tracer solutions for highly corrosive or contaminated services
ASTM B75/B75M defines strict requirements for chemistry, mechanical properties, expansion tests, hydrogen embrittlement tests, and non-destructive testing of seamless copper tubes.
What we provide
Material test reports (EN 10204 3.1) including:
Chemical analysis (Cu, P and residuals)
Tensile test results and hardness
Expansion / flattening tests as required
Eddy-current or hydrostatic / pneumatic tests where specified
Full traceability by heat, coil and bundle, plus packaging and marking aligned with ASTM / customer specifications.
Steam tracing design guidelines emphasize the use of 3/8" and 1/2" OD copper or stainless tube in long continuous runs for efficient installation.
Our advantages here
Soft-annealed C12200 coils with excellent ductility (typical O60 tensile 220–260 MPa with ≥40% elongation) allow tight wraps around process lines without wrinkling.
Level-wound coils minimize joints and leak points, reducing installation time and maintenance risk.
Global projects often mix ASTM, EN, JIS, GB and GOST documentation. Cu-DHP / C12200 has well-established cross-references to CW024A, C1220 and TP2 and to Russian M1F-type coppers.
We support
Cross-standard mapping (ASTM ↔ EN ↔ JIS ↔ GB ↔ GOST) in datasheets and certificates
Mixed-standard marking if your documentation requires both UNS and local designations
